Investigational malaria vaccine protects healthy U.S. adults for more than one year
PfSPZ Vaccine is first to show durable, sterile protection in people with no prior infection.
An experimental malaria vaccine protected a small number of healthy, malaria-naïve adults in the United States from infection for more than one year after immunization, according to results from a Phase 1 trial described in the May 9th issue of Nature Medicine. The vaccine, known as the PfSPZ Vaccine, was developed and produced by Sanaria Inc., of Rockville, Maryland, with support from several Small Business Innovation Research (SBIR) awards from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. NIAID researchers and collaborators at the University of Maryland School of Medicine in Baltimore, conducted the clinical evaluation of the vaccine, which involved immunization and exposing willing healthy adults to the malaria-causing parasite Plasmodium falciparum (P. falciparum) in a controlled setting.
